Why can't Telegram be installed with a simple apt\yum install telegram command from the official repository?

Question

linux

The main question is in the title.
I find some left repositories, after which apt update, apt intsall telegram can be installed, but how safe are they?
I know that you can just download the archive, put it in / opt / and everything seems to work.
Somewhere there was even a good guide so that it could be found in Ubuntu through a search. (lost it, maybe someone will throw it)

Answer 1

It is updated much more often than your repositories, and functionality depends heavily on updates.
Therefore, no one installs such things as browsers, instant messengers and other working software from the distribution repository. Put only non-priority.
Roughly speaking, it can be divided as follows: non-priority software - from stable sources, namely the distribution's repositories. It will probably be outdated, but you don't really need updates.
Priority software is from third party sources, it is less stable in the context of the system (it cannot be used as a dependency), but you need the latest versions.
That is why Telegram or a browser, even if they are in the repository of your OS, should be installed from the manufacturer's sources.

Answer 2

Because it is essentially a third-party and not particularly necessary program. And it makes no sense to strain those responsible for the packages, when they already have an issue and problems above a heap.

Answer 3

it is possible if telegram has an official repository
